1 Claims. (01.19'1-153) I This invention relates to adding machines or the like, and is "more particularly directed to means for moving the platen away from the printing elements and simultaneously swinging the inking ribbon in a position to render the same accessible for threading the free ends of the paper with respect thereto. 1

It is common in adding machineconstruction to utilize a double paper. strip fed from a single roll, and it is with the use of this type of roll that my invention is shown. When the double paper strip is used, a double inking ribbon is employed and the free ends of the paper strips are fedso that one of the strips will bedirected between the platen and the ribbon while the other is directed between the two ribbons. My'invention contemplates the use of a double ribbon and means for effecting a movement thereof upwardly and outwardly of the platen while efiecting a spreading of the ribbons.

In practice'it has been a rather tedious task to reach between the platen and the printing elements in order to properly'guide the free ends of the paper strips to their respective positions and it is to this end that my invention is directed.

I It is therefore the primary object of the present invention to eliminate this arduous task by manually positioning the platen in. spaced relation with the printing elements of the machine and to simultaneously swing. the inking ribbons to accessible position. I I

A further object is the provision of manually controlled means for effecting the movement of the platen and to simultaneously swing and spread the inking ribbons with respect to the a platen and the inking ribbons with respect to movement of the ribbons.

And a still further object is the provision of a pivotally supported paper guide for directing the outward movement of the paper strips from the platen, and which'guide serves when in position as a tear-off blade to sever one of the strips.

Referring to the drawings: I Figure 1 is a detail perspective view of an addof Figure 6.

As illustrated herein, the invention is shown as applied toan adding machine for'efiecting movement of the carriage and ribbon thereof.

The carriage designated as a whole as I0, is of u-formation'having a bottom wall II and side walls l2'and Iii. The bottom wall of the carriage I0 is provided with a plurality of elongated machine. v

The carriage Ill carries a platen lli which has -its shaft 2| journaled inthe sidewalls l2 and I3 and a paper table 22 'coacts with the platen for guiding paper strips fed from a roll A which is also carried on the carriage by a' shaft 23.

The usual feed rolls 2t coact with the platen 20 and are supported in a cage 25, (Fig.4), that is pivotally' carried at 26 on an'adjustable frame 21 which'is pivoted on a rod 28 that is supported in brackets 29, (one of which is shown), secured to the bottom wall ll of the carriage. A spring 30 is fixed to the frame 21" and to the bracket 29 2 aioaees and normally urges the frame21 and cage 25 upwardly with the feed rolls 24 thereof in contact with the platen 25. The upper portion of the frame 21 extends into the path of notches 3| arranged in a shaft 52 that is pivotally supported in the sidewalls l2 and. |3 of the carriage and this shaft has a lever 33 fixed thereto outwardly of the side wall l2 for manually controlling the movements of the frame 21 and cage 25 to efiect the disengagement of the feed rolls 24 with the platen 25. v i

As above stated, the carriage I5 is arranged for sliding movements on the machine by reason of the slots i4 and shouldered screws l5 and these slots |4 permit of a given forward and backward sliding movement of the carriage II, which, when moved forwardly, positions the platen in close proximity with printing elements 34, (Figs. 2 and 6), and when moved rearwardly, carries the platen therewith away from the printing elements, (Figs. 3 and 4) In order to eflect this forward and rearward movement of the carriage l5, 9. pair of L-shaped brackets 35 are secured to the bottom wall I I and each has a pin 35 secured thereto to each of which a link 31 is pivoted and which links extend rearwardly and are pivoted at 35 to an arm 39 and bell-crank 45, respectively, fixed to a shaft 4| pivoted in brackets 4|a' which are secured to 50 each of the side plates I5 and I5 of the machine. The bell-crank 45 has a handle 42 fixed thereto which may be manually gripped to turn the shaft 4| and arm 35 therewith to exert a pull on the links 31 and carry the carriage I5 35 for a rearward sliding movement. This rearward movement of the carriage carries the platen away. from the printing elements 34 providing a relatively large space therebetween.

The platen shaft 2| supports a pair of rock- 4o able members 43 and 44 outwardly of each of the side walls l2 and ll of the carriage and each of the rockable members is arranged to carry an inking ribbon guide member 45 and 45, re-' spectively, which is pivoted thereto at 41 and 45 45. A pair of upstanding pins 45 and 55 are fixed to the guide member 45 and a pair of upstanding pins 5| and. 52 are fixed to the guide member 45. These pins "-55 and 5|--52 serve 45 and 55 of the guide member 45 are normally aligned with each other and in spaced relation with the pivot 41 while the pins 5|52 of the guide member 45 are aligned radially of the pivot so 45. Theguide member 45 is arranged to swing in a clockwise direction from full line position to dotted line position as viewed in Fig. '1, while the member 45 is arranged to swing simultaneously therewith in a counter-clockwise direc- 55 tion from full line position to dotted line position as viewed in Fig. 7. Y

The guide members 45 and 45 are controlled for swinging movements by the rockable member 43 and 44 on which they are carried and when 70 in their normal positions, will retain the overlapped inking ribbon B in close proximity with the platen, and when moved to dottedline position, (Fig. '1), will spread the overlapped rib- Iron and retain it in spaced relation with the I platen.

. is rockedon the platen shaft 2|.

The rockable member 43 is of U-formation having upstanding integral apertured arms 43a and 43b through which the platen shaft 2| extends for pivotally supporting the same for rocking movements thereon. The rockable member 43 5 is provided with depending studs 53 and 54 which are aligned with the pivot 41, and these studs serve with the pivot to each support a pinion gear 55, 55, and 51, respectively, on the underneathside of the rockable member. The studs 10 53. and 54 loosely support the pinion gears 55 and 55, respectively, while the stud 41 has the pinion gear 51 fixed for turning movements therewith and this stud 41 is also fixed to the guide member 45. The'pinion gear 55 is in meshing l5 engagement with a segment 55 that is secured to the side wall l2 of the carriage I 5, and this segment serves to efiect a turning movement to the gears 55 and 51 as. the rockable member 43 The upstand- 20 ing arm 43b of the rockable member is provided with aninturned ear 430 to which one end of a tension spring 55 is secured and which spring has its other end secured to a pin 55 extending from the side wall l2 of the carriage. Thispln 25 55 also serves as a stop against which the upstanding arm 43b of the rockable member 43 normally rests. I

The rockable member 44 is of L-shaped formation providing an integral upstanding apertured arm 44a which has a bushing 441) secured therein for pivotally supporting the same on the platen shaft 2|. The rockable member 44 is also provided with an inturned ear 44c to which a tension spring 55a is attached and which spring has its other end secured to a pin 55a which also serves as a stop for the rockable member 44. This rockable member 44 has a depending stud 5| fixed thereto which carries a pinion gear 52 that is in mesh with a pinion gear 53 fixed to the stud which extends through the rockable member 44 and is secured to the guide member 45. The pinion gear 52 is in meshing engagement with a segment 54 secured to the side wall l3 of the carriage Ill. The rockable member 44 5 is relatively wide and carries a vertical shaft 55 which serves to pivotally support a ribbonspool 55. This ribbon spool 55 is provided with a gear 51 that is normally in mesh with a gear 55 fixed to the platen shaft 2| and as the platen 25 is actuated for a step-by-step movement to feed .the paper strips, as is common in. adding machines, the gear will effect a turning movement of the ribbon spool 55.

As thus far described, it will be noted that the 55 links 31, arm 35 and bell-crank 45 form a breakjoint when in the positions shown in Figs. 2 and 6, so that, as the handle 42 of the bell-crank 45 is manually gripped and rocked in a clockwise direction,the shaft 35 will be turned to break 0 this break-joint and the links 31 will then assume the positions shown in Figs. 3 and 4. This move ment of the links 31 will eflect a rearward sliding movement of the carriage II to carry the cause the rockable members to engage the pins 69 and during the rearward movement of the carriage, the rockable members will engage the pins 69 and be caused to rock about the platen shaft 2|. This rocking movement of the rockable members 43 and 44 is against the tension of the springs 59 and 59a and when rocked, the rockable member 43 carries the pinion gears 55, 56, and 62 therewith and the rocking movement of the rockable member 44 carries the pinion gears 62 and 63 therewith. As the pinion gears and 62 are in mesh with the respective segments 58 and 64, they will be caused to turn during this rocking movement of the rockable members. This turning movement of the pinion gears 55 and 62 is transmitted to the gears 51 and 63 which effects a swinging movement of the guide members 45 and 46. When the rockable members 43 and 44 and the guide members 45 and 46 are moved to the position shown in Figs. 3 and 4, the pin 49 of the guide member 45 is carried to approximately. 90 degrees and as this pin 49 is elongated as viewed in cross section, it will effect a spreading of the overlapped strands of ribbon. The pins 5| and 52 of the guide member 46 also serve to spread the overlapping ribbon to keep the same aligned with the spreading effected by the pin 49.

It will be noted that the guide members 45 and 46 normally lie in folded relation to the rock- 'able members on which they are carried, and

when moved, the guide member 45 will turn in a clockwise direction while the guide member 46 will move in a counterclockwise direction which will compensate for the outward movement of the ribbon away from the platen and still permit of its spreading movement, (Fig. 7)

This swinging movement of the, rockable members 43 and 44 also serves to bodily carry the ribbon B upwardly from the position shown in Fig. 2 to Fig. 3 position which is during the rearward sliding movement of the carriage l0. In effect, the overlapped ribbon will be caused to spread and move away from the platen during its upward movement and while the platen and ribbon are being bodily'carried by the carriage in spaced relation with the printing elements 34.

When the ribbon is in its raised position, (Figs. 3 and 4), the free ends of the paper strips A may then be fed around the platen and guided by the feed rolls 24 to the position shown in Figs. 4 and 5, and when in this position, the free ends of the paper strips may be directed by the finger (Fig. 5) to their respective positions, that is, one of the strips between the platen and ribbon, while the other is directed between the ribbons.

After the paper has been inserted as above described, the handle 42 is then rocked rearwardly to exert a force against the links 31 to restore the carriage III to its normal position. During this restoring movement of the carriage, the rockable members 43 and 44 arecarried away from the pins 68 of the arm 10 and the springs 59 and 59a will urge the rockable members to their normal positions and while being restored,

. the rockable members 43 and 44 and the gears 55 and 62 are rotated in a reverse direction by engagement with the segments 58 and 64 to restore the guide members 45 and 46 which will restore the inking ribbon B to the position shown in Figs. 1 and 2. When at the limit of its movement, the bell-crank 40 and arm 38 will again serve as a break-joint with the links 31 to retain the carriage Ill in its normal position.

After the paper has been inserted with respect to the platen and overlapped ribbon, the platen may then be rotated to cause a feed of the paper strips over the paper table 22, and at which time, a paper guide 1| is brought into position to guide the paper strips over the table and this guide then serves as a tear-ofi blade to sever one of the strips. The paper guide 1| is pivotal- 1y supported at 12-12 to thepaper table 22 and is provided with elongated slots 13-13 on each side thereof which permits of a relatively vertical movement of the paper guide. On each side of the paper guide is a spring 14 secured thereto and to the paper table 22, and this spring normally exerts a downward pressure on the guide to retain a notched-out portion 15 thereof into engagement with a shoulder 16 formed on the paper table. The paper guide 1| is provided with a cam edge 11 which serves to properly guide the "same to latched position after the paper strips have been properly positioned. This guide 1| is'preferably provided with a sharp edge 18 which extends its entire length and against which the top paper. strip may be severed while permitting the other strip to be fed over the paper roll A'and to a take-up roll 19 which is also carried on the carriage l0, and which take-up roll may be driven in anv suitable manner.

While I have shown my invention with an end- I less inking ribbon arranged in overlapped relation to form a double ribbon, other means such as two ribbons may be employed as long as they are bodily carried by the carriage and movable there-- with, likewise the segments 58 and 64 may be omitted and a series of arcuate perforations provided in side walls l2 and I3 of the carriage.
